How fossil animals were interpreted by rival sectors of British society, especially by pro- and anti-Darwinian factions. The ideological infighting was typified by T. H. Huxley and Richard Owen's clashes over dinosaurs, the ancestry of mammals and birds, and the kinship of mammal-like reptiles. Also discussed: William Henry Flower.--John Whittaker Hulke.--Harry Govier Seeley.--Charles Robert Darwin.--Edwin Ray Lankester.--Robert Edmond Grant.--John Phillips.--Ernst Haeckel.--St George Mivart.--William Boyd Dawkins.--William Kitchen Parker.--Herbert Spencer. First edition (ISBN 0-85634-121-5). The sales pitch for the subsequent University of Chicago Press edition (1984)--which contained minor corrections, mostly typographical--was "Biology Meets the Class War".
